Odd Language #158: Jacked Up

http://www.infoworld.com/article/3080037/linux/how-linux-mint-saved-the-day-for-an-ubuntu-16-04-user.html has a couple of sentences that looked odd to me: “I did install 14.04, only to find that the screen brightness settings were all jacked up. The machine booted with a very dim screen and you’d have to manually adjust it every time if you wanted to use it.”

The issue: The screen brightness settings were “all jacked up”. I read this as they were all set high, but the term “jacked up” can also mean “not working properly or as intended.” (See http://www.urbandictionary.com/define.php?term=jacked%20up.) In this case, the settings were all jacked up, because they were all set low.
